12.2 Freeboard Mark and Loading

  12.2.1 The freeboard mark applied should be positioned port and starboard at amidships on the load line length and may be an all-seasons mark. The mark should be a permanent disc and be of contrasting colour to the hull of the vessel in way of the mark.

  12.2.2 The fresh water freeboard allowance should be obtained by deducting from the all-seasons freeboard assigned, the quantity

where:-
Δ = the displacement in salt water in tonnes at the all-seasons draught
T = tonnes per centimetres immersion at the all seasons load waterline

Alternatively the deduction may be taken as 1/48th of the all-seasons draught of the ship at amidships.

  12.2.3 A vessel should not operate in any condition which will result in its appropriate freeboard marks being submerged when it is at rest and upright in calm water.
